Unknown self-hosted GitLab remotes were identified through a network-dependent authentication probe. When the host was offline or behind a disconnected VPN, provider discovery could wait for that probe even though glab already knew the host locally.

The GitLab adapter now first reads glab config get api_host --host <remote-host> during unknown-remote refinement. It preserves the remote host spelling for glab's case-sensitive configuration keys and accepts only matching normalized host/origin output, including the port. Failed config reads stay retryable. A successful lookup that does not match falls back to the existing host-scoped authentication probe, preserving token-based logins without api_host and separate API host/port configurations. Matching local configuration identifies the integration without validating its token. Ordinary authentication still uses glab auth status.

This retains @Exotic209093’s original contribution and commits, with current main merged. The shared discovery hook is already on main, so its obsolete hunks and duplicate resolver tests were removed. Fixes #17209.

Verification on headless Linux, Node 24:

66 → 63 focused tests across 5 → 4 files, all 63 passing on the revised implementation. The merged baseline had four stale-test failures against main's current callback, host casing and command shape. The PR-only core test file was removed; registry integration now covers actual routing, exact host keys, ports, rejected config and retry/cache behavior. Existing ordinary-authentication and Forgejo coverage remains. Token-login and separate API-endpoint regressions failed against the earlier candidates and pass with the compatibility fallback.
Restoring main's production implementation makes the offline registry regression fail; restoring the fix makes it pass. Production bytes were restored exactly.
Scoped GitLab/server typechecks, lint, formatting and diff checks passed. No repository-wide checks ran locally.
A real Ubuntu glab 1.36.0 binary was extracted into temporary state and run in a network-disabled namespace with synthetic configuration. Syscall tracing showed:

Command / configuration	Result	Connection/send attempts
Local config, exact mixed-case host and port	Matching host, exit 0	0
Local config, wrong host casing	Empty output, exit 0	0
Local config, unconfigured host	Empty output, exit 0	0
Authentication probe control	Reported unreachable network	Greater than 0

The local per-host lookup follows the glab config documentation. The isolated CLI experiment and production registry tests provide nonvisual proof; no client UI changed.

A second real-glab experiment used a synthetic token login without api_host and a loopback HTTP user fixture: the local config read was empty and the authentication fallback read the synthetic account. The production managed discovery service was also run with the real CLI: matching config selected GitLab after one local command; empty config and a separate API hostname/port both selected GitLab after the host-specific auth fallback against that fixture. This does not validate real credentials.

The original VPN/keyring-backed account, modern glab releases, macOS, Windows, iOS, Android and Electron desktop were not exercised here. Hosts without matching api_host retain main’s network-dependent authentication check. The offline improvement applies when the local value matches the remote host; it does not promise offline detection for separate API endpoints.

Review found token-login and separate-API-endpoint compatibility regressions. Both are fixed. Opus and Sol independently reviewed the full diff in three rounds; the final round found no code blockers and both reviewers passed all 63 tests. Reviewed/published head: 21e18ba60e. Latest-head CI is blocked: build/typecheck, lint, package tests and all eight server shards passed, but CI attempt 2 repeats a failure in WorkflowOpeningBlock.browser.test.tsx:103 (8047/8048 web tests pass). The unchanged web tree, shared client trees, lockfile and workflows match merged main exactly. A fresh test agent ran that browser suite alone: 3/3 passed. Lazy highlighter/Suspense readiness exceeding the assertion’s one-second deadline is the likely cause; precise CI timing is unproven. No web code or checks were changed. This PR remains blocked until the web CI gate is resolved.

Approvability

Verdict: Approved at cc7cae2

Macroscope's review found this PR approvable — This is a focused GitLab discovery bug fix that replaces a network-dependent unknown-remote probe with a host-scoped local configuration lookup while preserving existing authentication behavior and fallbacks. The production impact is limited and covered by targeted tests, with no schema, deployment, default, or diagnostic-suppression changes.

📝 Walkthrough

Unknown GitLab remotes are refined with a host-scoped glab configuration lookup. Core discovery now supports refinement arguments derived from provider context, while retaining static arguments and the authentication-argument fallback.

Changes: GitLab remote refinement

Layer / File(s)	Summary
Contextual refinement arguments `packages/source-control-core/src/server/discovery.ts`, `packages/source-control-core/src/server/discovery.test.ts`	`remoteRefinementArgs` accepts a static argument list or a function that receives provider context. Unknown-remote refinement uses the configured arguments, or falls back to `authArgs` when they are absent. Tests cover both forms.
Host-scoped GitLab probe `packages/source-control-gitlab/src/server/GitLabSourceControlProvider.ts`, `packages/source-control-gitlab/src/server/GitLabSourceControlProvider.test.ts`, `apps/server/src/sourceControl/SourceControlProviderRegistry.test.ts`	GitLab discovery runs `glab config get api_host --host <host>`. It derives the host from the provider base URL, or uses the provider name if parsing fails. Refinement requires a successful command and matching normalized hosts. Tests cover host casing, port retention, empty output, command failure, mismatched hosts, legacy username output, and self-hosted routing.

Priority: ➖ Normal

Estimated code review effort: 3 (Moderate) | ~20 minutes

Change: Bug fix · Severity of issue fixed: Medium

Merge Risk: ⚪ Minimal · up to e6ad4

The offline lookup identifies a remote only when its effective GitLab API host matches. No issue identified here needs to be resolved before merging.

Security architecture risk: 🔵 Low · up to cc7ca

The lookup remains tied to the selected remote’s host, and normal authentication checks remain separate. No security regression was demonstrated. Remaining uncertainty concerns how the real CLI selects credentials and hosts for subsequent operations when local configuration exists without valid authentication.

Retained concerns No architecture-level concerns identified.

Security review details

Security Blast Radius

inferred — The changed decision affects repositories whose selected remote is unknown and whose host has a successful nonempty glab user-config lookup. It can make existing GitLab operations reachable for additional locally configured hosts, but does not itself grant permissions at a GitLab service.

Trust Boundaries and Controls

observed — The remote influences a host argument to a fixed glab config command. That host is passed as a distinct argument, and returned config text is used only as a nonempty classification signal. The supplied tests assert lowercasing and preservation of an explicit HTTPS port.
observed — Subsequent MR-list and repository-API operations pass cwd without an explicit hostname. This behavior predates the PR. Repository source therefore does not settle which host and credentials glab selects for newly classified config-only contexts; credential redirection is not established.

Hardening Proposals

proposed — Validate the classification-to-operation handoff with a real glab installation using multiple configured hosts, a username without a valid token, and host-selection environment overrides. Confirm that subsequent operations target the intended host or fail without using another host’s credentials.

Full details: Linked Issues check

Explanation

Issue #17209 requires offline recognition of configured self-hosted GitLab remotes. GitLabSourceControlProvider now runs glab config get api_host --host <remote-host> and matches normalized hosts without a network probe. The shared discovery spec supports host-aware refinement arguments and preserves static and authentication fallbacks. Tests cover host and URL normalization, custom ports, empty or failed reads, mismatched hosts, legacy output, and fallback behavior. Normal authentication remains auth status. The separate caching work is not required by #17209.

Full details: Out of Scope Changes check

Explanation

The changes remain within issue #17209. Core discovery changes support the required host-aware command. GitLab, registry, and discovery tests verify the offline refinement and compatibility behavior. No unrelated product behavior or caching implementation is included.

GitLab CLI glab config get user --host fallback $USER v1.92.0 issue 8237

💡 Result:

1	Issue #8237 reports that in glab v1.90.0, `glab config get user --host <host>` could return the machine’s `$USER` environment variable instead of the host-specific `user` value. The issue says the fix was merged and the bug was resolved in glab v1.92.0: `user` is mapped to `GLAB_USER`, preventing `$USER` from shadowing the host setting. ([gitlab.com](https://gitlab.com/gitlab-org/cli/-/work_items/8237?utm_source=openai))
2
3	So if you’re seeing this on v1.92.0, the issue itself doesn’t establish why; it may be worth checking the exact command and configuration. By default, `glab config get` checks environment variables before config files, while `--host` selects a per-host setting.

Require host-specific evidence before refining the remote.

glab versions before v1.92.0 can return $USER for glab config get user --host. This code treats any successful, non-empty stdout as proof that the requested host is GitLab. The discovery flow does not enforce a minimum glab version, so an unrelated remote can be misclassified when an older glab version is installed. Gate this refinement on glab v1.92.0 or later, or use an offline check that proves the requested host has its own configuration entry.

✅ Confirmed as addressed by @Exotic209093

EExotic20909311d ago

Verified against glab #8237 and historical config/login source. A version gate alone would still allow GLAB_USER overrides. The follow-up instead reads api_host locally and requires its normalized host to match the selected remote. This keeps one offline probe and rejects nonempty unrelated/global/legacy username values. Added mismatched-host and legacy-output regressions; all 57 focused tests pass. Manual entries missing api_host remain conservatively unknown, documented in the PR.

CcoderabbitaiBot11d ago

@Exotic209093 Thanks for the clarification and fix. The supplied code now reads api_host and requires its normalized host to match the selected remote. This addresses the finding without a version gate or a network probe.

Leaving manual entries without api_host unknown is a conservative fallback.

Unknown-remote discovery uses one offline `config get api_host --host` probe and requires a successful result whose normalized host matches the selected remote. Manual configuration entries without api_host remain unknown by design.

Taking over this one for batch pull-request-10. I’ll keep unknown GitLab remote discovery local and host-scoped, remove the shared-hook changes already on main, and verify that normal authentication checks stay unchanged before pushing to this branch.

fix(gitlab): retain discovery for separate API hosts21e18ba

JJulius Marminge6d ago

Pushed the maintainer takeover as 21e18ba60e, preserving the original commits and merging main. Thanks @Exotic209093 for the local host-config approach.

The final change uses matching config as an offline fast path and keeps the old host-specific authentication probe for missing or different API endpoints. This preserves token-only logins and split API host/port setups, two compatibility regressions found and fixed during three independent Opus/Sol review rounds. Final reviews found no blockers; 63 focused tests pass, down from 66.

The body now includes real glab offline syscall proof and production discovery service runs for all three paths. @Exotic209093, confirmation with the original VPN/keyring setup would still be useful; no such account was available here. CI is pending on this head. Unmerged.

JJulius Marminge6d ago

CI remains blocked after one failed-job retry: attempt 2 failed only the inherited short-script highlighting assertion at WorkflowOpeningBlock.browser.test.tsx:103 (8047/8048 web tests passed). Build/typecheck, lint, package tests and all eight server shards passed.

Fresh independent diagnosis found the full web tree, shared client trees, lockfile and workflows identical to merged main; the isolated unchanged browser suite passed 3/3 locally. A one-second assertion deadline around lazy Shiki/Suspense rendering is a likely timing cause, not yet proven in CI. No GitLab change is indicated, and checks remain intact. The body records this blocker on 21e18ba60e. Handing back unmerged with the web CI gate outstanding.
